2 corresponds to my need

The 1000 watts are not so impressive as this, especially that it saturates at 80% (before I had a 300 watt)
But it's enough for my stay of 20 m2
It beeps in the room well with good spatial sensations, bass are not impressive, but I have not mounted the bass settings available by remote control.

The son to rear speaker are long, but I still had to extend with a son of my old speakers. It's pretty easy to lengthen because they are simple son (with red mark) to be inserted side walls.
Am not convinced by the Internet functions and the screen mirroring does not work better than my TV, I have not tried the blutooth, in general, I find the interface confusing human machine.
so I use it only as a 5 + 1 amp

With my Samsung TV, the TV remote to adjust the sound of the amp and the amp on and off simultaneously with the TV, suddenly we did not need the remote control home theater, really nice, I do not know if it's a function or Samsung would work with other brands.
